The brake command pressure is a control pressure, and a relay valve for carrying out capacity amplification based on this and outputting it to the brake cylinder is provided as a commercial brake system. There is a load valve which performs amplification and provides the output to the relay valve (see, for example, Japanese Patent Laid-Open No. 2000-272501).

In the conventional brake control apparatus described above, since the relay valve and the emergency load valve for emergency use have a separate structure as a separate structure, the pipe connection between them is complicated, and since the solenoid valve and the control panel are also provided, there are many parts. Therefore, there was a difficulty of requiring a large attachment space. Moreover, in FIG. 2 in patent document 1, when a control panel is arrange | positioned in the heat space of the upper side of a solenoid valve in a waterproof cover, there exists a problem that the control panel of the upper side is easy to receive the influence of the heat radiation from a solenoid valve. there was.
